Hi all
I'm trying to start your app, but I cannot understand what is going wrong.
Here you can find the docker and the config files
pango.zip
On cloudflare I've set the A record pointing to my IP, and just to be sure I've added also a A record for https://pangolin.thisismysite.com
when I start everything the docker logs for the 3 apps and everything is ok, but if I try to connect to https://pangolin.thisismysite.com, to https://thisismysite.com, or even to my internal ip address nothing happens.
How can I test where is the problem? Sorry but I have no more infos

Hello!
What do you mean nothing happens? Do you get any errors in the browser? If so could you post them?
Could you please also post your docker logs and remove anything you do not want shared? You can run
docker compose logs@Node815 commented on GitHub (Apr 1, 2025):
I'm facing the same issue, I pointed the A record to my domain in Cloudflare (I would love to get way from them) :) It's connected to an Amazon Lightsail VPS server. Here are the logs from the container:
When I attempt to go to my domain, I get a message that the server is down.
NOTE: I did select the "Free" instance with the 90 day trial so it's a very minimal provisioning on their side. It's a 512mb memory alllocation:
root@ip-172-26-14-92:/home/admin/config# free -m
total used free shared buff/cache available
Mem: 447 293 16 0 150 154
Swap: 0 0 0
I believe your docs say 1gb is recommended, so I'm not sure if this would have been the cause for this or not.

I'm sorry yesterday it was really late for me and I was really disappointed 😥
Now I'm more fresh and I can be more "usefull"
Hera are the logs
the services are running well
but if I try to connect to the site https://pangolin.thisismysite.com the browser goes in timeout if I go to the local ip I get a page not found... :-(
More infos are that I've tested the address on dns and the nslookup gives me the right IP.
Any other ideas I could try to test where is the problem?

Hi @pippo73,
did you open the ports 80, 443 and 51820/udp on your vps firewall?
If yes, could you also share your
/config/traefik/dynamic_config.ymland/config/traefik/traefik_config.ymlfile?Thanks
@pippo73 commented on GitHub (Apr 1, 2025):
The router is ok.
Here they are the files
and the second
@oschwartz10612 commented on GitHub (Apr 1, 2025):
Things look right so both of these issues make me think about firewalls. Are you 100% sure that the ports (443, 80) are open? Are you able to run a tcpdump on your VPS and see if any packets are making it when you visit the browser? If not you are not allowing packets through.
tcpdump -i any -n port 443@pippo73 commented on GitHub (Apr 1, 2025):
That was I thought too... but my question is: why if connect to my internal IP nothing happens?
If I go to http://192.168.1.113 at least something should happend on the browser or in the logs...
@oschwartz10612 commented on GitHub (Apr 2, 2025):
Traefik uses the host header to detect how to route to different things so it expects the domain in the host header for requests. When you visit with the IP address the host header is the IP and it does not know what to do.
@pippo73 commented on GitHub (Apr 3, 2025):
After long time spent with my ISP I've discovered that it was a problem of the network configuration of the router. Thanks for the help
